I thought it would be nice to have 4coder in an .app bundle on MacOS, so I quickly bundled it. Maybe you could have this as an additional download or something. Just a suggestion. Oh and the app bundle is not very tidy, just so it works.

Sorry, I should not have linked it like this. This page describes how an app bundle works. Scroll down, until you get to the Mac app bundle, don't try to create an iOS app bundle ;) Just read through this and here is the info.plist I used, so you don't have to start from scratch for that one.
